APPARATUS FOR MELTING AND MlXlNG BITUMINOUS COMPOUNDS.

SPECIFICATION forming part of Letters Patent No. 277,277, dated. May 8,18831 Application filed November-1, 18852.- (No model.) Patented inEngland October 4, IBSLNo. 4,297, and August 9,1882, No. 3,783. I

To all whom it may concern 7 Be it known that I, BRIERLEY DENHAM HEALEY,a subject of the Queen of Great Britain and Ireland, residing atLiverpool, in the county of Lancaster, Kingdom of Great Britain andIreland, have invented new and useful improved apparatus for melting andmixing bituminous compounds and like substances and treating the pungentgases therefrom, (for which I have obtained patents in Great Britain,No. L297, hearing date October 4, 1881, and No. 3,783, hearing dateAugust 9, 1882,) of which the following is a specification.

My invention relates to improved apparatus for melting and mixingbituminous fatty or similar compounds or substances, and for collectingand decomposing the pungentgases evolved in the process. The material orcompound is melted in a pan or boiler having a large surface exposed tothe heating medium, the gases being taken off by pipes communicatingwith the interior of pan and delivered to the flue. A piece ofwire-gauze is inserted in the gas-passage to prevent the gases fromfiring in the pipe and ignitingthe boiling substance, and is protectedfrom being choked, should the liquid boil up, by a float that rises andcloses the opening to the pipe. I provide a winged stirrer for mixingthe material or compound, and I place this low in the pan to assist inkeeping the bottomclean. 1 construct the fines over the fire-place withcurved fireblocks, and I also line the outer casing with fire-brick.

Referring to the accompanying twosheets of drawings,Figure is alongitudinal sectional elevation of the apparatus. Fig. 2 is ahalfsectional elevation of the same. Fig. 3 is a plan with chimney andgearing removed. Fig. 4 is a sectional elevation of the float-box andsliding wire-gauze frame. Fig. 5 is a plan of the same with the upperpart removed, showingthe wrought-iron frames in which the layer ofwire-gauze is inserted.

Similar letters refer to similar parts throughout the several views.

The inner or boiling 'pan, A, and the outer casing, B, Figs. 1 and 2,are in the form of truncated cones. The casing B is lined withfire-bricks both on its sides and bottom, except where the fire-bars arefixed.

The fire-place G is covered over with curved fire-brick covers, and theflue with an iron or steel plate, D, curved to the same radius as thefire-bricks. Beyond this a flat plate, E, is fixed with its further endresting on the firebrick lining of the outer casing. This plateis openat the sides to allow the heated gases or flame to spread out in eachdirection and pass round the pan on their way to the flue or chimney F.let branch Gr and the side of easing from being burnt away so rapidly.

The pan A is provided with a dished bottom, H, riveted into theshell,and has an outlet-pipe, Gr, terminating iu a plug-valve bolted toit. It is also provided with a footstep for carrying the vertical shaftJ, which has one or more stirrers, K,tiXed to it. The upper end of thesaid shaft runs in a bearingsecured to the lid or cover L, and is drivenby a pair of bevel-wheels from the shaft M, which is provided with ahandle, N.

Charging-holes P are formed on the cover or lid L, and are furnishedwith rings, lids, and hinges. The rings are of trough-section, with theinner flange higher than the outer one to prevent rain-water gettinginto the pan, and each lid has a flange which dips into the troughs, asshown.

' Opposite each charging-hole an overflowspout, R, is formed, the sidesof which are It also serves to protect the outmade of angle-iron, shapedto join and stiffen l the lid-plates, as shown in Fig. 3.

Cast-iron sockets W, Fig. 3,-are riveted onto the outer casing for thereception of movable shafts.

To the pan-top two cast-iron boxes or junc- I tions, S, Figs. 3 and 4,are bolted, the lower portion of each of which contains a cork float,

U, Fig. 4, fastened onto a small rod, by which it is guided.

' Two thin wrought-ironslidingpieces Z, Fig. 5, constitute a frame tocarry a layer of wiregauze interposed between the pipe T and the boiler,so that should the gas fire in the pipe T it will not ignite thecontents of the boiler.

The gas-pipes are led down by the side of the flue-casing F, and areinserted belovt the double-acting damper Y. This damper is furnishedwith a notched bar, and is so arranged thata portion of the heated gasesor flame may be directed direct up the flue, if desired, without passingunder and around the inner pan.

The fireplace door I, Figs. 1 and 2, is carried on horizontal hinges,and is provided with stops, so that when the dooris open it forms asill.

Under the back end of outer casing a crutch or stop, X, is bolted on forthe pan to rest on when in use.

The p'an Aand lid L are held in position by twelve (or other multiple ofthree) bolts pitched at equal distances, so that when one portion of thepan Ais wearing thin the bolts may be taken out and the pan itselt"turned round a third of a revolution, or one hundred and twenty degrees,thus bringing the boltholes true with each other again. The panbottomhas also three holes divided the same way, two of them being closed withblank flanges, so that the pipe G can be coupled up afresh to the pan Aafter the latter has been turned. By this means Wear can be equallydistributed all over the pan, and the whole material used up before itrequires to be repaired or renewed.

The whole apparatus may be mounted on traveling wheels and springs, andhave shaftboxes WV riveted to it for drawing it by horsepower. Thewheels are built up of wroughtiron, somewhat similar to ordinaryrailwaywagon wheels.

1 do not lay any general claim to the use, in apparatus for the purposespecified, of an inner boiler with an outer casing, as I am aware sucharrangements have before been proposed.

What I claim is- 1. In an apparatus for melting and mixing bituminouscompounds and like substances, the combination of a pan, a surroundingbrick-lined case, and one or more stirrers arranged within and near thelower part of said pan, so as to act both to mix the contents and tokeep the bottom clear of cakes or deposits of the material undertreatment, substantially as described.

2. In an apparatus for melting and mixing bituminous compounds and likesubstances, the combination, with a pan containing one or more stirrersand a brick-lined surrounding case, of a fire-place or furnace havingthe upper part covered with fire-blocks, and a layer of thick fire-brickopposite the exit end of the flueto prevent injurious action of theflame on the outer casing, substantially as described.

3. In an apparatus for melting and mixing bituminous compounds and likesubstances, the combination, with a pan with surroundingcase and flue,as above set forth,of a float, U, wire-gauze V, and pipe T, opening intosaid flue, substantially as described.

4. The combined apparatus for melting and mixing bituminous compoundsand like substances, comprising the pan or boiler A, with charging-holesP, overflow-spouts R, and stirrers K, brick-lined surrounding-case B,fireplace (3, flue or chimney F, with damper Y, and other parts, asdescribed and illustrated.
